Best: Episode 3: Great episode, filled with action, emotion, sorrow, figuring out how to get the train going, Seeing how things affect the characters, such a smart episode, well played telltale.
Episode 1: Even though it was a learning the ropes episode it was still a great episode, right from the bat it was exciting, and meeting the characters and forming relationships was well done. the whole animation of the episode was great.
Episode 2: I used to think this was the worst but having re-played it, it's grown on me. The whole scene of the farm when Lee and Mark are walking to the fences is a great image. The whole episode is filled with suspense, because you know the st johns are up to something but you don't know what. they took a risk having the antagonists not Walkers and it paid off.
Episode 4: I was very keen for this when i saw the trailer at the end of Episode 3 and while it still is a good episode it hit badly with a few vital things. 1: It's too long and does get a bit boring, and 2: Lee getting bitten killed the episode for me. I know i'll get backlash but i was hoping he wouldn't get bitten. I was hoping something unexpected would happen but you had a sense it would and when he was, you knew that was it. But some things did save this episode from being the worst, like Lee turning bad ass if you choose to threaten Vernon (funny shit) and The big house and the foggy setting is beautiful to look at.
Worst: Episode 5: Call me crazy and stupid but i just didn't connect to this episode. I thought the attic scene and Lee running through the horde of Walkers was entertaining but it just seems too rushed and not as much detail unlike the previous episodes. It's pretty much: Lee's bite affecting him, Losing the boat, Having 2 characters die (or 1 if Kenny is still alive) Lee turning badass, finding Clem, talking to the stranger who we all knew when we saw the car was from episode 2, Then the tear jerker at the end. i guess if they didn't have Lee been bitten they wouldn't of been limited but what can you do? I can't really blame it on the whole episode, because once Lee got bitten at the end of episode 4, you knew it was going to be short.
